When buying from a dealer, it's worth asking for a finance quote directly from them. Before that, though, get a loan quote from Rahalaitos too: it gives you something to compare the dealer's offer against, and a way to negotiate better terms.

Viewing quotes is free and doesn't commit you to anything. Rahalaitos puts your application out to as many as 25 lenders at once.

The APR under Finnish consumer protection law is 7.48%, calculated for a loan of €7,500 with a repayment period of 9 years, an account fee of €5, an opening fee of €35 and a nominal interest rate of 5.80%. The amount repayable would then be €10,215, i.e. €94/month. A credit card's APR may be 18.97%, calculated for a loan of €1,500 with a repayment period of one year and a nominal interest rate of 17.50%. The amount repayable would then be €1,646 in total, i.e. €146 per month. The final APR, loan term and monthly instalment are set out in the loan agreement. Lenders draw up the loan agreement based on an individual credit assessment. The nominal interest rate offered may vary between 4.19% and 20%, and annual loan costs between €0 and €150. The loan term offered varies between 1 and 20 years. Loan amounts offered range from €500 to €70,000.
